FIREPROOF FLOOR CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 738,496, dated September 8, 1903. Application filed September 27, 1902. Serial No. 125,121. (No model.)

T0 @ZZ whom, t muy concern:

Beit known that I, PATRICK T. SHIELDs, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented a new and useful Fireproof Floor Construction, of which the following is a specification.

My invention is an improvement in the construction of fireproof flooring, and has for its object the construction of such a floor in a durable and substantial manner at a comparatively moderate cost. f

I am aware of the fact that concrete has been used heretofore in various ways in the construction of reproof building; and my invention consists,l mainly, in the means' for supporting and bracing the flooring.

In` the accompanying drawings, Figure l is a sectional view showing my improved flooring. Fig. 2 is a plan view. Fig. 3 is a perspective view showing the manner of securing the tie-rods on a partition-wall. Fig. l is a detail of an anchor, and Fig. 5 is a modified form of anchoring the rods.

In the construction of my flooring anchors A, preferably V-shaped and having their ends A bent at a right angle to the body of the anchor, are embedded in the outer or main walls B of the building, the anchors of one -wall being in the plane of but out of alinement with the anchors of the opposite wall.

Divisional walls O, but one of which is shown in the drawings, are carried up to the level of the under surface of the proposed flooring and then extending about lone brick higher in the center, as shown at O.

Steel tie-bars D have their outer ends bentV the opposite wall extend similar tie-rods D3, which are bent around the bar E, intermedi ate the rods D. After the rods are placed in position `a flooring of concrete is laid in a plastic state and supported by stages, in the usual manner, until hardened. In practice I make this concrete layer between five and six inches in thickness, but the exact dimensions of the various parts would vary according to the size of the building. Uponthis concrete and intermediately over the wall O is placed the upper divisional wall O2, which supports `the iioor above. On the concrete and parallelI to the walls B O2 are placed strips F, which may be of either wood or metal, and resting on and secured to these strips is the iiooring G, which is preferably of hard wood, although it may be of any desired material. An air-space H is left between the flooring and the concrete intermediate the strips.

In Fig. 5 I have shown a modiiied form of anchor for the side walls comprising a steel bar I, similar to the bar E, the tie-rods being secured to it in the same manner as to the anchors A, and intermediate each tie-rod an anchor .I has one end bent around the bar I and the opposite end bent at an angle and embedded in the wall.

It is understood, of course, that the concrete fills the recesses B and extends across the building through as many divisional walls as may be used. l

Having thus fully described my invention, what I claim as new, and desire to vsecure by Letters Patent, is-

l. In abuilding, the combination with side and divisional walls, of tie-rods anchored at one end in the side walls their inner ends resting upon the divisional walls, a concrete iiooring extending through the divisional walls to the side walls, and means for securing the inner endsl of the tierods to the divisional walls.

2. In a iireproof building, the combination with side and divisional walls, of a bar resting lengthwise of the divisional wall, tie-rods anchored at one end to the side walls and bent around the bar at the divisional wall, of a layer of concrete resting on said tie-rods and extending across the divisional wall, and of an upper divisional wall resting on the con crete above the irst and adapted to support a second flooring.

3. YIn a fireprooil flooring, the combination with recessed side walls, of a divisional wall, anchors embedded in the sidewalls and pro- ICO jeeting into the recesses, a bar resting; on the divisional Wall, tie-rods secured to the side Walls at vone end by the anchors and bent around the bar at their opposite ends, a layer of concrete supported by the tie-rods and extending across the divisional Wall and into the recesses of the side Walls, strips laid on said concrete, and a ooring supported by said strips.

4. In a fireproof building having side .and divisional Walls, the combination With the recessed side Walls, of bars running` longitudinally along said recesses, anchors secured at PATRICK T. SHIELDS. Witnesses: l l
